Often times developers work with odd and even numbering cycles. I don't know if Canon does, but I suspect they do. So after the official release of 1.2.3, (ending in odd) they begin developing on 1.2.4 (ending in even). When 1.2.4 becomes stable they release it as 1.2.5. That type of numbering scheme helps keep from releasing their development version accidentally, until it done, tested, and signed off on. All the developers recognize from the numbers that it is the Work In Progress firmware they are working on and until it gets that increment to a odd number, it's not ready for release.

Has anyone ever seen an even numbered release for the 7D? I can't remember myself.

I think canon is not using this method. If you look here they use everything even and odd numbers. I think they just release a version test it if not good make a new version test it and when its good they release it to the public.

the checksums would differ if the file contents differed. If you have a *NIX machine around, OSX or Linux (or other *NIX flavour), you can compare, commands are md5sum <filename>, and sha1sum <filename>.

Thanks to the person posting the hash info. This convinced me that there is no difference in the first "leaked" version vs the "official" one..

Do you have an external CF card -reader? that way it should work easily.

Is the FIR file on your hard drive in your computer? Is there a cf card in your camera? You should be able then to copy the FIR file from your computer to the cf card in the camera and then update the firmware version. The installation instructions explain how to do this very well.

I always have an issue under Windows 7 x64 trying to do this where I can copy/delete from the DCIM directory but get a permission denied error trying to put anything in the root directory. I'm pretty familiar with Windows permissions and I've tried running explorer under administrator and can't get access to the permissions for the device. I've got 64-bit Windows loaded, Lightroom and the Canon utilities loaded so maybe one of those is doing something funky.

IIRC, there is a way to use EOS Utility for copying the firmware image to the camera. It should be described on Canon's firmware download page.

If that doesn't work, try using a CF card reader for copying the firmware file to the card. The camera itself doesn't support mass storage protocol, meaning that the USB connection can only be used to transfer image files (PTP protocol).

The contents of the card have no permission management since the cards are formatted with FAT32.
